Best expansion pack based on it's world?

City Livings getting my vote, it's the closest I've gotten to big world I can fill with custom Sims who get to know each-other much easier and naturally. Although some apartment effects are kinda frankly annoying to play under, especially ones that play sounds like Gnomes, but its also the closest feeling to Late Night's Bridgeport, nice big city skyline and some room to exist.

Sulani looks nice but it's not somewhere any of my Sims live by culture at all. Glimmerbrook and Forgotten Hollows are just too small, none of my wealthy Sims can ever move there without kicking someone out of their house. And Mt Komorebi looks lovely, fits in nicely with some Sims and more homely, but again a same issue where my wealthier Sims are also pretty much exempt from living there due to a lack of housing unless it's a vacation home
